- Discharge ports can be placed at 45 degree intervals and oriented in up to 8 different positions depending on your needs.
- It is often used if a short period of dry running is expected. Fluid is introduced into the area between the back of the seal face and the tight-fitting outlet on the drive side of the slurry pump.
- The terms slurry pump and dredge pump can be used interchangeably.

- What is a slurry?
- Slurry pump impeller, is one of the most important parts of centrifugal slurry pumps. Depending on the application, slurry pump impeller selection is crucial to slurry pump performance. Slurry applications can be especially hard on the impeller of slurry pumps because of their abrasive nature. In order slurry pumps operates efficiently and stand up to the test of time, impeller has to be selected properly for slurry pumps.
- Choosing the right material for a slurry pump is another key process in determining the right pump for handling slurry. If the slurry is highly abrasive with neutral pH, then the best material of construction is Hi-Chrome. this metallurgy has the highest Brinell hardness and can withstand the abrasiveness of the slurry.
- Aier Machinery has strong technical force and is specially engaged in the research of abrasion resistant materials of slurry pumps, sewage pumps and water pumps and the development of new products. The materials include high chrome white iron, duplex stainless steel, stainless steel, ductile iron, rubber, etc.
- The discharge branch can be positioned at intervals of 45 degrees by request and oriented to any eight positions to suit installations and applications. There are many drive modes for option, such as V-belt, flexible coupling, gearbox, hydraulic coupler variable frequency, silicon controlled speed, etc. Among them, the flexible shaft coupling drive and V-belt feature of low cost and easy installation.
- All products are mainly supplied to environmental protection, wastewater treatment, urban water supply and drainage, mine, metallurgy, coal, petrochemical, building material, thermal power FGD, river dredging, tailing disposal and other fields.
- The winch dredger is usually equipped with a hull-mounted dredge pump, which has an impeller centered at or below the draft line for further production and improved suction efficiency.
- We use CFD, CAD method for product design and process design based absorbing experience of world leading pump companies. We integrate molding, smelting, casting, heat treatment, machining and chemical analysis, and have professional engineering and technical personnel.
- Determine the perfect combination of slow pumping (to reduce wear) and fast pumping to prevent solids from settling and clogging.
- For pumping abrasive slurries, these types of pumps can also be made from specialised high-wear alloys. Hardened stainless steel is also a common choice for abrasive slurries.
- Keep in mind that slurry pumps are designed to adapt to specific pumping conditions. Pumps used in the cement industry handle most fine particles at low pressures, so the casing can be of lightweight construction. In rock pumping, the casing and impeller must be able to resist slamming, so they must be built thick and strong.
- Critical to the engineering of the pump are heavy duty bearing frames and shafts, extra thick wall sections and easily replaceable wear parts. Total life cycle cost considerations are critical when specifying pumps for severe operating conditions, such as FGD service. High chrome pumps are ideal due to the corrosive pH of the slurry.
- Pump selection for FGD
- The basic mechanical seal flushing programme is very simple. It requires that a clear/clean fluid (usually water) is introduced into the space between the actual seal and the impeller side outlet restriction. The flushing fluid is introduced at a pressure higher than the pumping pressure, thus ensuring positive outflow/flushing of the mechanical seal and a clean operating environment.
- A quench plan, as the name indicates, is designed to quench or cool the seal. It is normally used if short periods of dry running are expected. As illustrated bellow, the fluid is introduced into the area between the back of the seal faces and the close fit exit on the drive side of the pump.
- Corrosiveness of the slurry
- Another way of classifying the type of slurry pump installation is dry installation or wet installation. Dry installation pumps have the hydraulic end and drive located outside the liquid, whereas wet installation pumps (such as submersible pumps) operate within a catch basin or slurry. Submersible pumps do not require much support structure and therefore do not take up much space. Depending on the type of operation and installation required, the preferred method of pump installation is determined.
- Some quench seals are planned to replace the tight fitting outlet restriction with a secondary seal and a top outlet that can be piped to capture the used quench fluid and drain it from the rotating assembly. However the principle is the same, we try to cool the seal rather than flush it in any way.
- Pumps designed to pump slurries will be heavier than pumps designed for less viscous liquids because slurries are heavy and difficult to pump.
- Rubber lined pumps offer many advantages
- Is the discharge configuration suitable for abrasive slurries?
- How to Succeed in Slurry Pumping?
- For certain types of slurry pumping conditions, positive displacement pumps may be a more suitable option than centrifugal pumps.

- 2.Pumping slurries poses several challenges and problems, but with proper engineering and equipment selection you can experience many years of worry-free operation. It's important to work with a qualified engineer when selecting a slurry pump because slurries can wreak havoc on a pump if not properly selected.
- Submersible Slurry Pump
- Slurry Pump
- - transport solids hydraulically
- All manufacturers are consistently involved in product development in the long and short term. Customers should expect to benefit from these developments in a number of ways: increased efficiency, increased reliability, reduced operating costs, or a combination of both.
- The concentration of solids in the slurry - measured as a percentage of the total volume.
- Less downtime
- Traditionally, centrifugal pumps are used to pump highly abrasive slurries. Centrifugal pumps use the force generated by the rotating impeller to impinge kinetic energy into the slurry.
- Rubber is lighter and softer than other wear lining materials. This aids installation because it is easier to lift and install quickly and efficiently. Positive results for the health and safety of workers in the field.
- From an operational point of view the stuffing box is different as it requires some leakage to ensure lubrication and to prevent heat build up. The mechanical seal box should be leak free.
- Better safety
- Quenching is defined as the introduction of a neutral fluid (usually water or steam) into the atmospheric side of the seal to prevent the formation of solids that may interfere with movement or be used for other purposes.
- Slurry Pump
- Typical Applications of slurry pump
- A typical pump solution for this application is to install a hard metal >slurry pump to withstand these types of conditions. Hard metal pumps need to be able to withstand the most severe abrasive slurry service and they also need to be designed to be extremely easy to maintain and safe.
- These conditions include
- Fine-grained sand can be extremely abrasive and typically wears slurry pumps quickly. Characteristics of coarse aggregates that can affect pump performance are size, shape and surface texture, as well as gradual changes in particle size, while fine materials can create excessive friction in the pipe.
